Debian Packages

Debian has a carefully planned and controlled release program and has
a number of releases available at any time. The releases have
code names (originally
from the Toy Story movies), release names, and
versions. This may sound
complicated, but it is actually quite simple and effective. The
officially released and current version of Debian is referred to as
the stable release. This release is regularly highlighted as the most
stable GNU/Linux distribution available.
